Title: Apparatus for obtaining percussion sound waves for medical diagnosis
IPC: A61B7/02
Filed: 1935-09-02
Abstract: 461,700. Percussion sounding-apparatus; stethoscopes. TAYLOR, C. W. Sept. 2, 1935, Nos. 24467 and 24468. [Class 81 (ii)] Percussion sounding- apparatus for medical diagnosis and for testing articles for cracks, flaws, and the like comprises walls forming a chamber surrounding the position struck by a plexor which is operated automatically by mechanism outside the chamber, the soundwaves produced being led to the ear or ears of an operator. The apparatus may comprise a rigid wall which is contacted with the person or object to be tested and which is struck on its inner face by the plexor, or the latter may make immediate contact with said person or object. A plexor or percussor 18 operates in a sounding chamber 20, its stem passing through the roof to a compartment 22. Clockwork mechanism is mounted between plates 11 fixed outside the compartment and rotates a cam 15 shaped to coact with a projection 16 at the end of a lever 14, the other end 17 of which engages the end 23 of the plexor 18 and raises it against the action of a spring 2 adjustable by a screw 24a to vary the power of the percussions. The wall 25 which is struck is placed on the person or article tested. The sound waves pass by an orifice 21 and tubes 26 to earpieces 27. The revolution of the cam 15 is checked when the projection 16 clears the cam surface by means of a controlling member 19 on the lever which follows a path coinciding with the contour of the cam. The member 19 also causes the lever and plexor to break contact at the moment of percussion. The struck wall may be of cork with an inserted brilliant, glass crystal, knot of wood or other type of pleximeter, or may be slotted so that sounds such as heart action can also be heard. It may be removable or adapted to swing out of position, when the apparatus can be used for both mediate and immediate application. Means for automatically starting or stopping the plexor when contact with the person or material examined is made or broken, or for making a definite number of strokes and then stopping may be provided. The concussions may be caused to increase or decrease automatically by providing above the spring 2 a cam operated by worm gear. A partition of silk or other material may be fitted to prevent discomfort to the listener's ears. In some cases, the walls of the sounding chamber other than the struck wall may be vacuum jacketted. The plexor may be put out of action and the apparatus used as a stethoscope or phonendoscope. A number of plexors may be provided for application to different parts of an object or to several objects simultaneously. Sound-amplifiers such as microphones may be incorporated or the apparatus connected with means for producing records.

Abstract: 162,313. White, J. F., and White, W. H. Oct. 8, 1919. Passing loose fibrous material through fluid-applying apparatus.- Wool is passed progressively through a washing-machine by rotating drums having tangential beaks adapted to keep the wool constantly immersed. As shown, the material is passed over a series of consecutive concave surfaces 3 by drums 6. The surfaces are formed by curved perforated plates forming a false bottom to the vessel 1. The feeding-drums have circumferential parts and beaks 7 formed by radial and tangential parts, and are mounted in an adjustable frame. The vessel 1 is divided by pyramidal bases 9, so that one part may be emptied independently of another part. The wool is fed by a conveyer 8, and is sprayed with water from a pump 12. On emerging from the vessel 1, the wool is subjected to a water spray 18, and passes through squeeze rollers 19 to an opening-drum 21, which is similar to the drums 6 and which passes the material on to a conveyer 22 to a second washing-machine or to the drying-machine. According to the Provisicnal Specification, the surfaces over which the wool is passed may be formed of plain surfaces used with triangular members preferably having curved sides.

Title: Process for the production of pyridoins and pyridine aldehydes
Filed: 1951-10-23
Abstract: In a process for the production of pyridoins and/or pyridine aldehydes, homologues of pyridine together with up to four times the theoretical quantity of an oxygen containing gas, the theoretical quantity of oxygen being based on one molecule of oxygen per methyl group contained in the said pyridine homologues and if desired an inert diluent, are passed in the vapour phase at a temperature above 250 DEG  C. over an oxidation catalyst comprising at least one oxide of a metal of subgroup a of the fifth, sixth or seventh groups of the periodic system, out of contact with iron oxide or copper oxide.  The invention also comprises 6 : 6 - dimethyl - a  - pyridoin and 6 - methyl-pyridine-2-aldehyde. Corresponding pyridine aldehydes are obtained from a -, b - and g -picolines and 6-methyl-a -pyridine aldehyde is obtained from 2 : 6-lutidine.  Mixtures may be oxidized, e.g. technical b -picoline containing b - and g -picolines and 2 : 6-lutidine may be oxidized to to obtain 6-methyl-a -pyridine-aldehyde, g -pyridine aldehyde and b -pyridine aldehyde. Dialdehydes may also be obtained.  From 2 : 6-lutidine pyridine monoaldehyde or pyridine dialdehyde or a mixture of these compounds may be obtained depending on the proportion of oxygen used. Trimethylpyridine may be oxidized to a mono- and/or dialdehyde and 4 - methyl - pyridine - 2 : 6 - dialdehyde may be obtained from 2 : 4 : 6-trimethylpyridine.  Insert diluents mentioned are carbon dioxide and/or water vapour.  Preferred catalysts are oxides of molybdenum and vanadium. separately or in combination.  The catalyst may be supported on carriers such as pumice, silica gel and active alumina, the catalyst being precipitated on the carrier or the carrier may be saturated with the appropriate ammonium salts and heated.  As furnace materials aluminium tubes, precious metals or nickel or ceramic materials are preferred.  In examples: a -pyridoin is obtained by passing vapours of a -picoline and water with air over a catalyst comprising molybdenum oxide, initially ammonium molybdate, or silica gel at elevated temperature in an aluminium tube (1); a pyridine aldehyde is isolated from products obtained by passing at elevated temperatures vapours from an aqueous solution of a -picoline over a catalyst comprising molybdenum trioxide and vanadium pentoxide on silica gel and in a similar manner are obtained 6 - methyl - pyridine - 2 - aldehyde from 2 : 6-lutidine, g -pyridine aldehyde from g -picoline and a mixture of b -pyridine aldehyde, g -pyridine aldehyde and 6-methyl-a -pyridine aldehyde from technical b -picoline (3) and a mixture containing b - and g -pyridine aldehydes is obtained on passing vapours from an aqueous solution of b - and g -picolines with air over a heated catalyst, prepared by treating with ammonia silica gel to which manganese chloride has been added and heating the product. Specifications 563,273 and 563,274 are referred to.

IPC: H01J13/48
Filed: 1927-09-21
Abstract: 277,972. Hewittic Electric Co., Ltd., (Assignees of Becq, A., Hewittic Soc. Anon., and Demontvignier, M.). Sept. 21, 1926, [Convention date]. Vapour apparatus, arrangernents of. - In a mercury-vapour rectifier means are provided (a) for protecting a bimetallic element for the starting electrode (b) or opening the circuit of the element after starting, and (c) for ensuring closing the output circuit only after starting has been effected. As shown in Fig. 1, a bimetallic element 3 operating a starting electrode 5 is enclosed in a protective screen 7 of glass or other insulating material. The electrode 5 is of tungsten, and slides in a glass sleeve 8 having a flange supporting the screen 7. The element 3 is adjusted so that when the rectifier is in operation the end of the electrode 5 is at the surface of the mercury so as to localize the cathode glow. After starting, the heating current of the element 3 is opened by a relay, and the potential of the electrode 5 remains the same as that of the cathode. As shown in Fig. 3, the secondary winding 22 of a transformer is connected in series with the starting electrode 5 through a resistance 23 and the contacts of relay 26, the winding of which is shunted across the rectifier by a connection through an inductance 18 with the cathode, and through a resistance 25 with the neutral point of the primary 20 of the transformer supplying the anodes 10. The shunt circuit maintains the arc. A circuit breaker 27 in the output circuit has its winding controlled by the contacts 28 of a maximum current relay in the output circuit or by contacts 29 controlled by the winding 26 so that (a) the circuit-breaker cannot be closed when the rectifier is not started across its shunt and (b) in case of failure of the alternating current supply the rectifier cannot be started on load. In the arrangement shown in Fig. 4, the arc is maintained by auxiliary electrodes 33 connected through inductances 34 with the secondary of a transformer 32. The heating circuit of the electrode 5 is opened at. the contacts 37 of a relay 36. The output circuit has a circuit-breaker with a winding 42 controlled by a maximum current relay 41, by contacts 38 of the relay 36, and by push-button switches 45, 46. Auxiliary contacts 43 in the circuit-breaker shunt the switch 45 and control the insertion of a resistance 44. Gratings or casings around the anodes may be connected by relays to the cathode or anodes so as to present starting under load. In order to prevent the passage of continuous current through the starting electrode a condenser may be included in its circuit.
